---------------------------------------

             Summary: Message.getCMSMessageID() returns an empty string after send
                 Key: AMQCPP-482
                 URL: https://issues.apache.org/jira/browse/AMQCPP-482
             Project: ActiveMQ C++ Client
          Issue Type: Bug
          Components: CMS Impl
    Affects Versions: 3.6.0
         Environment: Windows 7 service pack 1, ActiveMQ broker 5.8.0, apr 1.4.6, apr-util
1.5.1, apr-iconv 1.2.1
            Reporter: Jonathan Fortier
            Assignee: Timothy Bish


The JMS specification states the following:
"When a message is sent, JMSMessageID is ignored. When the send method
returns it contains a provider-assigned value."

However, when I use ActiveMQ-cpp to send a message, it returns an empty CMSMessageID after
the send operation completes.

Looking a little deeper for the problem, I saw that in ActiveMQSessionKernel::send(...), if
the message doesn't need transformation, we clone the message before sending it. However,
the message ID is set on the clone rather than on the original message, which could explain
why the original message stays with an empty CMSMessageID.

To reproduce the bug, I used the "example" application that comes with ActiveMQ-CPP, and I
added the following line in HelloWorldProducer::run(), after sending the message:
  printf("Sent message with ID: '%s'\n", message->getCMSMessageID().c_str());
This always print an empty ID.

I wanted to retrieve this ID to later match a response to a request sent by ActiveMQ-cpp,
and I didn't find any workaround to retrieve this ID by other means...
